I'll look at that.  I did that to the IC-3210.
Just stare at the schematic for a long time and
find a good suspect for a lead that changes
state between 2m/70 cm.  Then get a scope or
meter and verify that it goes high/low at the
proper time.  Then attach a cooperating buffer
and a relay driver.  On the 3210 I found a way to
use the required current to pull up the antenna
relay, but use less current to hold it up.  The
relay doesn't run hot that way. It was a 12-volt
antenna relay.          73  Clete
